At the same time, the box with specimens determined as  agnatain ZFMKcollection is supplemented with an additional label " Typeverloren" [ Typelost]. Obviously, the typesof  Acronycta agnata, as well as the most part of the collection of M. Draudt, which was located in Darmstadt, Germany, have been destroyed during the Second World War. Because of  A. dignaand its closest relative  A. metaxanthahave overlapping geographic ranges in China, the neotypedesignation is necessary.
